Indication of the work the climate control version 1
The repetition of the description:
Another hack which allows you to show the led temperature and a heater-air-conditioner.
How it works:
Duct temperature sensor is installed. A temperature sensor is a conventional thermistor that can change its resistance from temperature. Next, the controller measures the temperature of the temperature sensor by the ADC and indicates the work of the tri-color led. If it is above 25 degrees, then the red. If below, then steady blue. If in the area of 25 degrees, the light is white. The color transition is smooth. At forty degrees and above — pure red. At 10 degrees and below — pure blue.
Display white color in two ways: the mixture of red, blue and green (RGB led), the second option is to use a white led instead of green. I like the second option more because it gives a more pure shade of white. Therefore, in the garland you can work with RGB led and Trinity blue-white-red led.
The second version of the differences:
Changed the connection of the thermistor, now it is connected between the minus sign and the ADC input. It's more convenient to change the mode of operation is now sufficient to jumper the thermistor.
Appeared dimmer: when 12 volts on the dimmer (input IMAGE), the brightness decreases by half — comfortable with night driving.
When power is applied the LEDs lose, "greeting": alternate gradual buildup and decay of blue, green (white) and the red led.
Appeared printed circuit Board: four inputs — four outputs. On the one hand connected LEDs, on the other — the power and the temperature sensor. The outputs for the LEDs sharpened by standard RGB tape
Top — thermistor
Option on the factory signets:

UPD 25/04/2015 updated the firmware, added a white balance mode.
Sample setup: www.drive2.ru/l/8530168/
Importantly, implemented, and come up with what is always possible: in Winter, turned on the stove, but the system has not warmed, that would be the person in the glass is not blowing cold air, turned and watched when they turn red.
30 three rubles - a penny? Izlishne it. 99% digital and is very different thermometers come with a temperature sensor on a conventional thermistor. And the sensor type ds18 popular only beginners mikrokontrollerov who need their knowledge to use in working with 1ware bus

It would be unnecessary and roads
the Chinese, he is worth a penny

well, for just glow shift yeah unprofitable
but if the glow is combined with a thermometer that would be cool
and could be combined with temperature meter with display and remote three-wire digital sensor?
then I would buy
to put in my push button control unit stove
Read the default factory fuses and change the value of these two bits to the opposite value
fyuz how to sew ! The tune, I sew everything . Inverse or straight stitching and how to put it, jackdaws to remove or put BODLEVEL1 and SKDIV8
hmm! A good answer ( . This is clearly the case with the tester ! But it is not working ! Turn on the blue light blinks once and for all
Good evening. You have transistors in the circuit 47К, and on the signet are looking 10K. What to believe?
Yeah, just most people do collect, and very few buys it, I have not posted it there
